Elemental Fiend, Waterfiend

This elemental
creature resembles a cone with three sides. Each side sports a single
arm, leg, and face. In each arm, the creature carries fierce-looking
weapon. Each face seems to be identical and all are twisted in
terrifying grimaces and constant spout obscenities in a strange
language. Each face has glowing eyes.

SPECIAL ABILITIES

All-Around Vision (Ex)

An elemental fiend's three faces allow it to see in all directions at once. It cannot be flanked.

Freeze (Ex)

A waterfiend deals cold damage in addition to damage
dealt on a successful hit in melee. Those affected by the freeze ability
must also succeed on a DC 17 Reflex
save or get frostbite, taking 1d6 cold damage for an additional 1d4
rounds at the start of its turn. A freezing creature can attempt a new
save as a full-round action by shivering and rubbing their arms and legs. Creatures that hit a waterfiend with natural weapons or unarmed attacks take cold damage as though hit by the waterfiend. The save DC is Constitution-based.

Willful Weapon (Su)

A disarmed elemental fiend can will its weapon to return to its hand on its turn as a free action,
as long as the weapon is within 30 ft. of the elemental fiend and is in
its line of sight and line of effect. The weapon automatically returns
to the elemental fiend's hand even if the weapon is being held by
another creature.

ECOLOGY

An elemental fiend is a rare creature from one of the elemental planes that takes the form of a roughly human-sized
pillar of its native element. Upon first glance, an elemental fiend
strongly resembles an elemental of the same size, but beyond that the
resemblance ends. It has three faces, three legs, and an arm between
each face. Each arm wields a masterwork melee weapon of unknown origin.
Its three faces constantly scowl and scream at opponents, howling and
babbling vulgar curses in its native tongue.

An elemental fiend attacks primarily with its weapons. It positions
itself in such a way as to bring as many weapons to bear on a single
opponent as possible. Because each face controls an arm, it can attack
with all three weapons in one round without penalty. An elemental fiend
cannot battle a single opponent with more than two of its weapons, but
it can battle one, two, or three different opponents at the same time.

Waterfiends are typically found on the Plane of Water. Their weapons are masterwork tridents forged of an unknown blue metal. They are constantly cool to the touch and are immune to cold damage. They have wave-like designs that run the length of the handle.
